It makes no difference if the lease specifically allows seismic testing. The Texas Courts have held that the full exploration rights clause by its nature grants that right, so silence as to seismic grants the right. Contrast with Louisiana, where the right to conduct seismic has to be spelled out in the lease form itself.
For you to block them, your lease form would have to specifically state that no geophysical rights were included in the grant, or that the Lessor expressly reserved all rights to conduct seismic surveys, etc.
My lease form is framed to reserve the seismic privileges. That way we have much more control with a Seismic Data License, i.e. single use, term, damages if not performed, access to data, ability to grant multiple Seismic Data Licenses etc.
I doubt that you can trade up.
If you are the surface owner, the real approach that might have been made to you is to request access across your surface. They have that right, anyway, but will always want a permit, so that liability and damages can be set, along with other things -- gates locked, no trash or debris, etc. Without a Surface Permit, they could not use any improvements to the property, such as roads, bridges, etc.
